` WHEEL-raorNdMAcrtl-NE.

To all whom z' may concerni' Be it known that' LIGARLAND F. KrGH'r, a citizen of the United States, and a resident of Norfollnin the vcounty of Norfolk and State of Virginia, have invented new and useful Improvements in Wheel-Facing' Machines,of which thel following is a specication. l Y

My? invention is a wheel facing machine and is designed for the purpose of facing of the hub of the wheel 'truly with the wheell or facingthe hub so that the .inner and Vrouter faces of the wheel rimvwill be exactly parallel with the lopposite faces of the hub.`r -Another-important object of the invention resides 'inthe' provision of Ya krotatable table'upon which thewheel to be faced or tire surface of the lhub level.

,It vis also :within the',V provisions of the present inventionto pro'videlaV combined hubV facing and wire-y wheel truing machine Mounted upon the under face of the table bevel gear 13' revolublef wherein the mechanismissuch as to be mo'- mentarily interchanged -for operatingv upon the hub of a wooden wheel orto true a wire wheel.'

Myinvention further embodies a rotatable wheelsupporting table and a cutter or planing element which is advanced step by step across the face' of thefhub to cut or u plane the hub at a different point after each' revolution of theV table', this being 'accomplished through the instrumentality of al mechanism'actuated by the table rotating mechanism.

It has also been myendeavor to improvise a machine vpossessing the preceding fea- V tures and others that may be outlined in thel following specification-and at 'the same time providela machine which is comparatively 'simplein construction and may be manufactured and sold at a nominal cost.

Theinvention, as reduced topractice, consistsin the combination' ofvelements, construction and arrangement of parts opera-- tions and specific details which willbe here'- inafter enlarged uponV and recited inthe subjoinedclaims andillustrated in the attached drawings wherein- 1 r Figure 1 is a side elevation of a wheel hub facing lmachine constructedin accordance Specification of Lettersv latent.:

A horizontally disposed guide barv or track 2O disposed directly above the ,tableflO andV inparallelism with the bar 14, this bar being rectangular in cross section and termi# natingin ears.21, one of which is engaged upon -the upperend ofthe shaft 8 and isv retained thereon by a nut 22threaded upon this" shaft. The opposite end is engaged uponthe reducedthreaded end Y23 of the vertical bar 15.` A nut 24 isthreaded upon this reduced end and retains this end ofy the bar rigid with the bar 15.

VA tool holder or carriage, 2'5is provided' whichI tool holder or carriage. isformed from an elongated block of metal and is provided with a transverse rectangular opening 26 at its upperend'wlnch receives the bar and is movable longitudinally of this-bar.

`Referring to thewire spoke wheel truing machine illustrated `in Figs 3 there is illusf trated afrusto-conical member 33 Arotatably mounted upon a fixedvertical shaft 34 upon the stand 5. Extending vertically from the upper face'of the truste-conical member 33r y and at its `center is a threaded stemrll.

Asillustrated in the drawing the frusto-` conical hubof the wheel is received onthev frusto-conical member 33. A circular ynut 35de threaded upon theV stem 34:` and has its lower end beveled, as indicated `at', to

fit within the smaller end of thehub lof the wheel. With the parts in-.thisrposition and upon tightening the nutB the hub will lbe forced home i and retainedin this position `until the spokes are tightened in the usual gageblade it i's swungto a `horizontal posiis to be taken as a preferredeXample of theysame, vand thatvarious changes'in the .shape,s1ze and arrangement ofparts may manner.
